Not done this before so apologies if it is in the wrong place.
I have a 2011 fiesta zetec with a gold pack which includes factory fitted front and rear parking sensors. This morning on my 2nd trip out in it when I turned it over there was an alarm inside that lasted about 8 seconds ish, quite loud and not like a car alarm or my parking sensors more like a police siren.and had 2 different noises going off. then started it again to see if it did it again, it did and I noticed the light on the parking sensor button was flashing and the sensors didnt seem to be working. I got to work and now it isnt doing it. have booked into Ford tomorrow to run a diagnostic but the service guys nor customer service have ever heard of it before. Just wondered if any one on here knew what it would be??? .. just to make me more concerned there have been some break ins using an electronic device the last few nights in our area and wondered if this may have caused it...thanks in advance. (ps no other faults or dash lights, no sign of break in and parking sensors working fine now)
